When the locomotives returned, it's inspected for collision or derailment damage, in addition to normal things like measuring wheels, checking brake rigging, etc. Also, a check is made to see if all removable parts (such as chains, tools, fire extinguishers) are intact. Normally, though, locomotives that are leased to another road are already well-used, and it's the lessee railroad that really needs to do a careful inspection on the lessor railroad's "one-owner" locomotives before accepting them.
During the term of the lease, the Federal blue card will identify the lessee as the operator. The lessee is responsible for all required periodic inspections and repairs. If the lessor is responsible by contract for maintenance, then the lessee is responsible for returning the unit to the lessor railroad before the next mandated inspection date.
It's not so formal in the case of pool agreements. Only if there is an issue with repeated scavenging of removable items or fresh derailment/collision damage is there an issue. If there is major damage (wreck damage or a major component failure), the railroads agree, on a case-by-case basis, who will make repairs. Routine maintenance to off-line locomotives in pool service is done at a standard charge and billed to the owner road.
